1. Hibernate+EHCache - Non-cached entity cached after insert    forum.hibernate.org

I am trying to use 2nd level caching for Hibernate with EHCache. I have some entities configured in the application that I have tagged with @Cache and I see that they are used by EHCache correctly. However what I have observed is that when I save/update any other entity that is not supposed to be cached; I see that it gets ...

3. Caching, dynamic-update and dynamic-insert    forum.hibernate.org

On some discussions of caching (I am using EHCache), I see dynamic-update="false" and dynamic-insert="false" set as the attributes for a hibernate class mapping. Are these two attributes required for caching to work properly? I have not seen this explained anywhere, at least not yet. I have a secod question. I have a Lookup table, SomeLookup. Within SomeLookup, I have all the ...

4. insert Collections and cache    forum.hibernate.org

I would like to start a discussion about inserting collections and cache At the moment hibernate will treat a collection creation like and update in respective to caching. it will invalidate the CacheEntry. This is a huge performance nag as the first read of that collection will always go to the database. In my case there are 100s of concurrent reads ...

5. Caching objects when inserted    forum.hibernate.org

hello I'm using the latest Hibernate release with EHCache as a second-level cache. All settings are pretty much default. The app uses very simple bean-like objects with no association, but the rate of writes and reads is very high. I turned statistics on and noticed that I have 0 second-level cache hits for selects, so apparently all objects are fetched from ...

6. second level cache on insert    forum.hibernate.org

Does Hibernate 3.05 cache an object in the second level cache on insert? We are using DB2 version 8.2 along with the read-write cache. We're noticing the objects are not cached on the insert but they are cached after the first lookup. I stepped through the insert code and I did not find any logic for placing objects in the second ...

7. Second Level Caching and inserting new data    forum.hibernate.org

Here is the code snippet. Transaction transaction = null; session.setFlushMode(FlushMode.NEVER); transaction = this.session.beginTransaction(); transaction.begin(); session.saveOrUpdate(object); this.session.flush(); if (transaction != null) { transaction.commit(); } session.evict(object) closeSession(); open anther session. session.list(query); The list return a different result then what is in the database. The update is fine. I am using EhCache. I tried various options like turning off query cache, second level cache ...

8. inserting data manually and 2nd level cache    forum.hibernate.org

ew0kian wrote: if i'm using 2nd level cache... and i manually insert some data into the db via command line (not using a hibernate session)... will the cache return old data to users? If you are inserting then no because the data didn't exist before but I assume you are talking about updating data that is cached in a L2 Cache. ...

9. Inserted Object is not being cached    forum.hibernate.org

Hi, I persist a new object into database through Stateless / Stateful EJB (tried with both of them), and then try to select all objects through cacheable query, it does not retrieve objects from the cache. But if i do not insert anything and just select, everything works fine. I use JBoss Cache for L2 caching, is it a normal behavior? ...
